extend active admin to prettier boolean values

active_admin.rb

# It extends activeadmin to show pretty boolean values
# 
# config/initializers/active_admin.rb

module ActiveAdmin
  module Views
    class TableFor
      def bool_column(attribute)
        column(attribute){ |model| model[attribute] ? '✔'.html_safe : '✗'.html_safe }
      end
    end
    class AttributesTable
      def bool_row(attribute)
        row(attribute){ |model| model[attribute] ? '✔'.html_safe : '✗'.html_safe }
      end
    end
  end
end

# example
# app/admin/user.rb

ActiveAdmin.register User do
  index do
    column :name
    column :email
    bool_column :admin
  end
  show do
    attributes_table do
      row :name
      row :email
      bool_row :admin
    end
  end
end

Very handy, and easy to appreciate. Thanks.

Forgot to mention, also added an IndexAsTable class to the Views module to work with ActiveAdmin 0.5.1

class IndexAsTable
  def bool_column(attribute)
    column(attribute){ |model| model[attribute] ? '✔'.html_safe : '✗'.html_safe }
  end
end

Thanks very helpful. I was looking for it.

I would suggest the following edit (though honestly not 100% that args.last always returns the attribute:

module ActiveAdmin
  module Views
    class TableFor
      def bool_column(*args)
        column(*args){ |model| model[args.last] ? '✔'.html_safe : '✗'.html_safe }
      end
    end
    class AttributesTable
      def bool_row(*args)
        row(*args){ |model| model[args.last] ? '✔'.html_safe : '✗'.html_safe }
      end
    end
  end
end

I ran into the need for this with renaming columns like bool_column 'Paid?', :is_paid.

And use this code if you just want to show the booleans with status_tag in AttributesTable view (no need of changing column methods to bool_column:

ActiveAdmin::Views::AttributesTable.class_eval do
  def content_for(record, attr)
    value = find_attr_value(record, attr)
    if is_boolean?(attr, record)
      value = status_tag(value)
    else
      value = pretty_format(value)
    end
    value.blank? && current_arbre_element.children.to_s.empty? ? empty_value : value
  end

  def is_boolean?(data, item)
    if item.respond_to? :has_attribute?
      item.has_attribute?(data) &&
        item.column_for_attribute(data) &&
        item.column_for_attribute(data).type == :boolean
    end
  end
end

its really helpful....i am looking for it from last two days
